Karl Dungs FRI Pressure Regulator
The Karl Dungs FRI pressure regulator combines the functions of pressure regulation and a filter in one housing. In addition, the FRI has (2) downstream pressure ports for gas switch installation or pressure sensing. Can be installed as a stand along regulator, or incorporated into a Karl Dungs DMV style pipe train.
- UL, CE and CSA certified.
- Lock up style regulator, so no downstream pressure builds up under no flow conditions.
- The FRI double diaphragm design and vent limiter eliminates the need for vent piping outside a given building.
- The FRI will handle up to 7 PSI maximum inlet pressure.
